Hi, I will be visiting from Boston Columbus Day weekend. I'm staying in Palo Alto, and am planning at least one daytrip to SF. Sadly, I missed the Chowhound picnic deadline. I'm looking for restaurants that have a high level of deliciousness inversely proportionate to the total bill. I like every kind of food, but must avoid mango-reliant cuisines, as my immune system dislikes mangoes with an intensity that scares even me. Thanks in advance!
