There are a couple of cafes down Old Street in P'burg with outside seating. French pastries, quiches etc. If you haven't discovered Old Street you'll find shops and a great place making chocolates to die for. With ocean at your back it's right of the main dock, an alley on the left with a crescent sign over the street that read's "Old Street". There's an old yellow car in the street and a good jewelry store at the left corner of Front & Old sts.

Chesterfield's near the cruise ships has great breakfast reasonable. Dinner's are good too but never had lunch there.

Greenhouse near Bobby's Marina corner of Front St has lots of great aptzs to share.

Not cheap but reasonable is the outdoor garden seating at the Passaangrahan hotel. From the boardwalk it's just before the curve toward the cruise ships. From the street it's beyond Old Street. A beautiful old hotel where the Queen of Netherlands stayed. Building was shipped in pieces and constructed---the first "pre-fab." Friends had what they said were great burgers there. We've only eaten dinner there but great atmosphere.

Just meander try some of the little places you might pass then tell US what was great. I doubt you can go wrong.
