In town from LA for the weekend. Staying in Union Square and looking for a place within walking distance (it can be a long walk) that's fun, lively, open (relatively) late, and not too expensive (entrees in $10-15/range). Obviously, it would need to be a place that we could get in w/out a reservation--we are fine with eating at the bar, and in fact, sometimes prefer it.
Like all types of food, and will be eating at Pesce Sat night, so prefer something of a different style.
Thanks in advance!
