restaurants : my fave...
as i live in the 1st arrondissement and have previously lived in the 13th, my fave are of course Asian places of all persuasions (meaning Japanese, Thai, Chinese, etc... nothing to do with the customer's personal tastes ;-)
one thai restaurant i can recommend for sure is SukoThai, a wonderful pocket-sized thai place near Place d'Italie. Make sure you make a reservation over the phone - the place is (alas) too popular now and is almost always full, even on Tuesday evenings and such !!!
it is located on rue du père guérin, which is a side street near place d'italie (u need to hit on rue Bobillot, then make a right at the first street on the right, and there you are)
