Bostonian who will be in the city for a night. Sounds lonely, but that's how attending conferences are. Any recommendations for places within walking distance from Sutter/Powell (less than 20 minutes)? How lone-diner friendly are places like Scala's, Cafe Claude, and Canteen (or any other places I should consider)? I'm not a wine drinker (!) so great wine selection isn't a factor. I'm not looking for a crazy singles scene, just a excellent meal to enjoy by myself.
btw, it doesn't have to be european/american cuisine (that just seems to be the kinds of places in Union Square). If there are suggestions, I'd also appreciate bahn mi, pho, HK-style congee/noodle or ramen places with the same walking distance criteria.
