Bruxie's is also in downtown Brea, next to Edwards Cinemas. I agree, go to Tap's, that place is amazing. Cha Cha's is also good, while Berkeley Dog is also in that same complex for good hot dogs
Also, there is D'Vine Mediterranean food in the Target shopping center, Olive Pit next to the Wal-Mart on Imperial Highway...there is Flappyjack's on the 55, get off at Tustin Ranch and turn left; that has BOMB breakfast...
If you go to the Hat, get the fries with chili cheese...will feed 6!
On State College Blvd there's What's Up Men (Ramen joint, not gay bar
no insult intended), Pielogie, to name a few.
You can eat at Tommy Bahama's restaurant in Corona del Mar (I think) if you want to drive.
BTW - I dunno if it's still operating, but just avoid the Tut's Bar and Grill in the Embassy Suites. Went to hell years ago.
You're also not far from downtown Fullerton, which has a good tapas bar, Heroe's Bar & Grill, Spaghetti Factory (meh), a good steakhouse whose name I forget right now, and lots of bars and lounges to hang out in.
