Tips from locals
If you want a quick bite, these are your people. Unique sandwiches are a plenty here.
My favorite destination for breakfast, this is a local chain. Their coffee is great (buy a bag of 100% PR coffee to take home) and the sorullitos (corn sticks) are a perfect complement for sandwiches.
This is a Puerto Rican attempt at Subway. Quality breakfast and lunch sandwich options that wont break your budget. Good quick in and out type of restaurant. The second floor is a good place to bring your laptop and work out of the place.
