For Italian, the best place in town is Zanotti (IMHO), on Soi Saladaeng across and down a bit from Anna's Cafe. Also, Ciao, outside on the waterfront at the Oriental Hotel is hard to beat for atmosphere this time of year. Gianni on Soi Ruam Rudee is also good.

For Indian, Pasand at the mouth of Sukhumvit Soi 12; the Tandoor at the Holiday Inn Crowne Plaza; and Rang Mahal on the rooftop of the Rembrandt Hotel at Sukhumvit Soi 18.

For German/Swiss, Chesa on Sukhumvit Soi 20 wins hands down.

I don't care much for French, but people seem to like Le Banyan on Sukhumvit Soi 8, which is well known for its pressed duck and elegant atmosphere. Also, Le Bordeaux, at Sukhumvit Soi 39, is popular (and gay owned). Cafe de Paris on Patpong II for bistro-style food.

For Middle Eastern (Lebanese), Moody's Place in Sukhumvit Soi 5 is fantastic.

For Greek, Athena in Sukhumvit Soi 63 (Ekamai), up near the Phetburi intersection is the only game in town, and very good.

For breakfast/brunch, Crepes and Co on Sukhumvit Soi 12 -- great pancakes and crepes. For hotel buffet brunch, the Sukhothai on Sathorn Road is good for a splurge.

For coffee and desserts, Kuppa on Sukhumvit 16 has cheesecake to die for.

And for Thai...too many to name! Some of the more accessible ones for non-Thai speakers/readers: Anna's Cafe (Soi Saladaeng), Baan Klang Nam (on the river on Rama III Rd), Kannicha (Sukhumvit 11, behind de Meglio's), My Choice (Sukhumvit 36), Ton Khrueng (Sukhumvit 55), Supatra's River House (for atmosphere more than food), Cabbages & Condoms (Sukhumvit Soi 12). And, of course, any place that looks good on the street, probably is!
