Okidoki - Tustin (has wide variety of diff japanese food: noodles, sushi, yakitori, hotpot); I love the spicy udon that comes in a fiery stone pot
Crack Shack - Costa Mesa (bomb fried jidori chicken)
Miyabi Shabu - fav shabu place in irvine currently cos the meat quality is very good for the angus choice (even compared against the $80 wagyu they had)
North Italia - pasta (very nice date place, and pasta's yummy since made from scratch)
Habana @ spectrum is actually good as an inexpensive brunch place at their bakery section (with cuban sandwiches, pastries, those fried potato balls Porto's known for, coffee)
Moulin - Newport Beach (French brunch place)
Hive & Honey Marriott Rooftop bar was cool to check out since it's the only rooftop bar in Irvine. Good view, but drinks were a bit pricey (no cover tho!)
Shinsengumi - Irvine (since it closes at 11pm, and one craves ramen/udon a lot when everywhere in Irvine closes)
Bruxies - Irvine (always has $5 wednesday specials, and lately has everyday $7 chicken tender deal)
Happy Hours in Irvine:
Habana - Cuban restaurant in spectrum ($5-6 drinks and small plates)
Brio Tuscan Grille - Spectrum (nice sangrias and $5-6 drinks and small plates)
Tokyo Table - DJ
