Tibits is very vegan friendly. On the food boat each item has a sign saying if it vegan or contains lactose etc. A lot of the items are vegan. You choose the food you want, then take a bread roll (which is included in the price) and then take your plate to the counter for it to be weighed and the you pay according to weight of the plate.
At present, every 10 days is Vegan Day (eg 7th, 17th and 27th August 2014), so on that day ALL the food on the food boat is vegan! As to which day is Vegan Day see the current list on the website: http://www.tibits.ch/en/food-drink/blog/detail/items/vegan-days-at-tibits.html
On Vegan Day there can be three vegan cakes on the food boat (inc sticky toffee pudding, victoria sponge, and perhaps chocolate cake)as well as vegan mousse.
At the counter where you pay there are also some cakes but only one of them is vegan - last time I went it was lemon cake and it tasted great. This cake is served by the slice, and for about £1.90 or so can be cheaper than getting cake from the food boat.
They also have tubs of ice cream in a freezer by the door. The Booja Booja chocolate one is vegan.
Tibits is licensed to sell alcohol. They list their wines on a board behind the counter and those that are suitable for vegans are clearly marked.
Tibits is one of my favourite London vegetarian restaurants. The London Vegan Meetup Group as well as the London Vegetarian Meetup Group often have events here.
They have outdoor seating as well as seating indoors (ground floor and downstairs)so quite a spacious restaurant.
Final note. If you're on a limited budget don't put too much food on your plate as it could be costly. In an evening I usually pay £12 - £15 for a plate of food. It's slightly cheaper at lunch time.Pros: Buffet with great tasting food, Lovely spacious restaurant , Very vegan friendly
Cons: Not sure how much it will cost till pay, Outside can be smokey
