Gianni, 3333 Bear St., Costa Mesa. The bar is open 10 a.m to 10 p.m. Monday through Saturday and 11 a.m to 7 p.m. Sunday. (714) 540-3365. A mall bar that offers sightseeing as a chaser. Perched a few feet above the slippery main drag of Crystal Court, and tucked inside an Italian restaurant, this bar offers a Kodak view of bustling shoppers and a peaceful respite from the masses. It may be the next best thing to a Sharper Image store for killing time. Tia Juana's Long Bar & Mexican Cafe Deluxe, 14988 Sand Canyon Ave., Irvine. The bar is open Sunday through Thursday 11 a.m to midnight, Friday and Saturday till 1:30 a.m. (714) 551-2998. Housed inside a restored 95-year-old lima bean warehouse, this is the kind of cavernous bar where you might actually have room to breathe. Order a cerveza (they claim to serve any Mexican beer you can name) or a hand-shaken margarita and pretend you're inside some upscale, south-of-the-border restaurant that actually has napkins.
