Thank you this deff will help. I am staying at the new courtyard Marriott on Lakewood blvd.My wife and I live in Long Beach; some of our favorites are:
The Crab Pot - located on the Marina. She loves the crab there. They offer fresh catch (which varies) and the steak is quite good as well.
Chen's - Located on Broadway, and also has the RinkRat seal of approval.
K.C. Branaghan's - Tasty Irish fare in a place reminiscent of an old world pub. Taken guests there and the feedback always positive. Smithwick's on tap.
Belmont Shore area
George's Greek Cafe - Excellent food, friendly staff. Greek wines available.
Panama Joe's - Good Mexican offerings and libations. Also has bar with live music, if that's your thing.
Belmont Brewing Co. - Right by the Belmont Pier; award winning craft beers, wide ranging menu and patio dining overlooking the beach.
For a quick, casual lunch if needed, try -
Charo Chicken - (PCH, just south of the Traffic Circle). Best chicken in the city, either the pieces or other Mexican-inspired dishes.
The Aquarium area has the usual; Outback Steakhouse, Gladstone's, P.F. Chang's and some others.
Good luck with your get together! The Aquarium area is closer to the Queen Mary, but the others (save Charo) I listed are in nice areas along the coast and not really that far.
Where are you staying?
