I'd been meaning to try this place for a long time and whilst out shopping with a friend at Bluewater today, we decided to give this place a try for lunch. The website proclaims that "everything is cooked to create the tastiest burgers out there." I disagree; my friend actually makes the world's best burgers, but they were certainly tasty.

We arrived at around 12.15, so fairly early for lunch. A few people were already seated, but there were lots of empty tables and we were seated straight away into an American-style diner booth. It was comfortable with plenty of room and we were most amused by the ketchup bottle - it was a red tomato. I can't really say much about the decor of the place, as it was at Bluewater shopping centre - although it was in one of the food courts, it didn't have it's own unit, so to speak. However, tables were spaced apart and had plenty of room and were clean.

The waiter was very perky and came to take our order straight away. They have a good selection of burgers; a selection of various beef burgers, lamb burgers, chicken burgers, salads, some specials and what I thought was a really good selection of veggie options. We opted for cornchips with salsa, avocado and sour cream to start with, along with a portion of olives and I ordered the Buffalo burger, whilst my friend went for a burger with crispy bacon and avacado.

The corn chips came with our drinks literally within the minute. We were very impressed and the corn chips were delicious - very more-ish. There was a large portion, loaded down the toppings and we got stuck right in. I can't comment on the sour cream as I loathe the stuff, but my friend said it was just like anywhere else. The avacado came as guacamole - not the best I've ever had, as I like chunks of onions and garlic in mine, but it was tasty nonetheless. The salsa was the standout - tangy on the tongue, but chilled so it had a cooling contrast. It was very tomato-y, with garlic, well seasoned with chilli and loaded with kidney beans and onion. It had a lovely chunky, crunchy texture and was fantastic.

We had to wait ages for the marinated olives and eventually had to ask for them. They eventually came out with the burgers, which defeated the point of having them for a starter and when they came, we were disapointed with them. The portion was quite large, easily enough for two people to share and there was a good selecion of olives, along with pepper, garlic and baby gherkins (ugh!). However, we were expecting them to be marinated in olive oil, but they tastied very much like vinegar and were quite soggy - we ended up leaving them.

The burgers on the other hand were fantastic. My Buffalo burger came in a crispy bun, with crunchy lettuce, tomato and onions. I had asked for no mayonaise and was pleased that they'd got it right. The burger itself was delicious - large, juicy and succulent. It was very meaty and there was not a hint at anything other than quality meat. I recommend, however it was one of the more expensive burgers on the menu at £9.95, and I could not tell much difference between it and beef, so you may choose to save a couple of pounds by going for a normal burger.

My friend's burger also looked great, coming with crispy, streaky bacon, avacado, lettuce, tomato, onion and mayonaise. After attempting to bite into it and everything sliding out (I told him so) he eventually got his mouth round it and declared it delicious.

Most of the burgers come in two sizes, although there are a few exceptions, such as my burger. The 'low rise' are 4oz burgers and the 'high rise' are 6oz. Greedy it may sound, but my burger was 6oz and I think that this is probably the right size, as the quality is so good, you want to really savour and relish it. Chips are available as a side for £2.95, however we found the burgers to be enough. We did see some being taken to other tables and the portions did not seem overly big for the money.

We did not have dessert - we didn't ask to see a menu and it wasn't offered. Looking at the website, I don't think that they do them, which is a bit of a let-down as lots of people like to have desserts when they eat out. Of course, this could be part of a plan to get as many people in and out as possible throughout the day, but I think this a mistake.

In total, we paid just over £30 for the two burgers, olives, corn chips and two beers. Yes, it is more expensive than Macdonalds but the quality IS that much better. I've certainly paid more for much worse meals.

All in all, I enjoyed my meal at GBK. I'm not sure I'm in a hurry to go back immediately, but I would certainly give them another go. Vouchers for 2for1 meals at GBK are widely available, so I'd recommend grabbing one of those and giving it a go.
