London mid May (vegan restaurants) on the Southbank? – and more

My wife and I will be in London in mid May. She will be there work-related and I’m coming with her just for fun / old-times sake (apprentice in London in the late 70s) / to visit the Imperial War Museum. The latter is the only fixed item in my agenda. (I wrote about this earlier and was given great advice on that matter from people here!)

Our hotel is located on the south side of the river; the Hoxton Southwark. Close to Tate and the IWM. The company has an agreement with Ennismore who owns the Hoxton hotels.

We’re looking for two spots to have dinner. On Sunday and Monday evening. Nothing fancy; jeans and sneakers accepted and -if possible- with vegan dishes on the menu or totally vegan. Google gave me some addresses with satisfying reviews, but I guess it would be better to ask here. Dinners are not on the company’s bill. We pay for it ourselves. My wife holds a position where she will not mix private expenses with company expenses.

Apart from that: if you happen to have nice ideas how to spend the best part of 2 days in the region of the hotel on the Southbank (I prefer to walk), well… don’t hesitate to drop them here.
