Best chef's tasting menu restaurant that has a chef's table as well
L'Espalier. Chefs table is set up in the kitchen. IIRC, price starts at around 200/pp and they will consult with you beforehand regarding the menu (likes, dislikes, # of dishes etc). They are very accommodating. They only have 1 seating per day excluding Sunday.
