The Broadway Cafe is a must visit. I think of it more as visiting a relative than as a restaurant experience. Nicole, the owner, is a character. Engage her in conversation, find out what the specials are. She might have something that doesn't appear on the menu. While some of her Japanese dishes are very good, I recommend the Vietnamese dishes. Her fresh spring rolls, pho, sandwiches (banh Mi), and her chicken curry are all excellent.
Pros: inexpensive, great vietnamese dish, informal homey atmos
