This place is fantastic; I've been three times and thoroughly satisfied each time. There are three vegetarian/vegan burgers on the menu: Thai pumpkin basil, Moroccan chickpea on cornbread, and nut burger. I believe that the nut burger is the only one that isn't vegan, as it has a yogurt dressing, but I have tried all three and they are all DELICIOUS, not to mention HUGE! The Thai pumpkin is definitely my favourite, though. It's 5 euros for just the burger, prepared fresh for you upon ordering, and for 9 euros you get two big sides of fries and salad. I've had friends say that the tomato soup was also quite good, and there is a selection of fairly-priced hot and cold drinks. The service is good; friendly, young workers, but there are a few faults: if you go too early in the day they may not have all of the burgers prepared to cook yet, there's a bit of a wait after ordering since they cook them fresh (especially if they're busy), and sometimes they run out of certain burgers by the end of the day (including the meat patties).
The atmosphere of the place is really great, as well - funky style and mis-matched furnishings, menus written on chalkboards, and there's an upstairs seating area that looks just like someone's antique-furnished living room. Plus, it's part of the art gallery and has all kinds of cool events going on all of the time.
If it were possible I would rate BeatBurger with 5 cows, but I can't since it isn't strictly vegetarian. It is definitely still HIGHLY RECOMMENDED!Pros: AMAZING food, Big portions, Friendly staff
Cons: Sometimes run out of certain burgers, Closed Mon-Tues
