For neapolitan, Antico Pizza or STG Trattoria
For neo-neapolitan, Ammazza
For NY, Rosa's pizza in downtown.
For something more adventurous, I recommend these Buford Highway spots
1. Quoc Huong (Vietnamese sandwich, etc)
2. Bobo Garden (Cantonese). Order the salt and pepper squid and/or the crispy garlic fried chicken
3. Ming's Garden: order P5. The crispy pork
4. Gu's Bistro: tea smoked duck. many other tasty stuff in menu. Very very HOT.
5. Quickly: Bubble tea
