Port Jefferson ?
Salsa Salsa is a pretty good place. It's not an authentic Mexican restaurant, but they always have really good specials and their soups are amazing. Their portions are huge too. A good deal for the money. Their website is salsasalsa.net
The Tiger Lily cafe is great. It's a bit small, but during this time of the year it shouldn't be too busy. They make excellent sandwhiches. I love their provencal sandwhich. They also make really great fresh fruit and veggie juices. Their website is tigerlilycafe.com
We were totally unimpressed with Salsa Salsa.
Our favorite place right now is The Pie, coal oven pizza and everything else Italian. People have told me they love Pasta Pasta across the street, but I've never been myself.
Used to love Costa de Espana, are they still there? Very continental feel.
