My own side of the river? I live in East Dulwich! He's more Forest Hill way. There are a couple of good quality Indian restaurants but some of the others are not. It's so sad to walk past them, particularly mid-week when they have 1 table in or no customers at all. My friend was going to pay the owner 50% of the food profits to cover rent of the kitchen he was offered. I do know some others that do a kind of pop-up in pubs that have been very popular. Agreed, it'll be best to go in and ask at the restaurants themselves though. I just posted on here to get opinions whereas he'll be the one asking around. Not sure whether street food fits his style but then the Northcote road market is going from strength to strength and would be a good starting point.
