How about dinner at a Russian Deli in Walnut Creek? Location is near Broadway Plaza with its own parking lot.
Menu offers starters like piroshky and antipasto, soups like borscht where I've seen it served at a Jewish deli at the Mirage in Vegas. Dinner entrees are stroganoff, blintzes, chicken kiev, crepes and plov which is rice slowed cooked with lamb, tomato, parsley and dill. There are an assortment of wonderful desserts. I grew up dining on this type of food so it all sounds delicious to me.
There's also music & dancing available with performance stage & sound system but I've never been to this restaurant so not sure if they have music mid week.
Come outside your box and join the group for a wonderful evening!
