I'm a college kid major food lover looking for some recommendations for some sweet SF dining. From august 10-17 my mom, younger sister, and I will be visiting for a week. We'll be staying in the financial district and, while we're definitely looking for at least 2 or 3 nice, somewhat expensive places (maybe I can finagle one really amazing meal), I'm primarily looking for the affordable, adventurous, and indispensable san francisco spots. Most of my time during the day will be spent wandering around either alone or with my 16 year old sister, so we're really free to do some exploring. We will eat basically anything, so if anyone can recommend some food trucks, markets, some casual lunch spots, or really anything that would make our experience there delicious and exciting.
