We are staying in the gaslamp district for a weekend in August with our 7 month old baby. We've been taking her to restaurants since she was a few days old, and she always does great. She loves watching the action with us. We eat early at lively restaurants or on restaurant patios. We don't limit ourselves to "child friendly" restaurants (i.e. chains) but we don't take her to really quiet, romantic type places either. If they have high chairs, we'll be there.
Is Acqua al 2 a very quiet restaurant? or is it lively enough that most people won't notice a well behaved baby?
Alternatively, are there other restaurants that are busy on Friday/Saturday evenings within walking or short drive from the Marriott? We love authentic Mexican, Italian and grill food.
