short time lurker from San Diego here and I thought I'd throw in a few opinions:
1)Anthony's may be touristy, but I have NEVER had a bad meal there.Ever.Which is more than I can say for some places
2)When in Hillcrest, go to the City Deli.Slightly on the pricey side but you gotta love how they have have a
thing of pickles on all of the tables.Mmmm,pickles :)
3)Avoid the 101 Cafe in Oceanside.When I first moved to Oceanside I used to go there all the time,but the quality of their food, and of the service,has gone in the toilet.Ruby's,out on the end of the O'side pier, has better food *and* better service to say nothing of a great view.Another good place in Oceanside is the Longboarder Cafe.
4)I hear lots of good things about Buca Di Beppo.I haven't been there yet(going there for my birthday actually).
