Mediterranea serves the best falafel in New Haven. Of this I have no doubt. For one thing, I watched them prepare my falafel pita ($3.50); the guy did it with such care and precision that I felt almost guilty---he was working way too hard for an item that costs less than $4.
The ingredients are high quality. They use a wholewheat pita wrap (a massive improvement over white flour anything) which adds a robust taste to the consumed whole; the falafel pieces themselves were crisp, full of herbs and just plain delicious. The tahini sauce is thick and rich and actually tastes like sesames, not like watery sesame residue (which is the case at places like Mamoun's and Kasbah). Tomatoes and a variety of lettuce (maybe even some spinach) added to the taste.
This is the type of place that would do well to cater more to vegans, like me. If they had some mock chicken wraps, or maybe Daiya vegan cheese to go with their pizzas, I'd be back every day.
Similarly, if Mediterranea were open later (it's only open till midnight Monday-Thursday, and it's closed on Sundays) I'd be there all the time. As it stands, I am excited to have found decent falafel in New Haven; Mamoun's, Kasbah and Aladdin are all decent, but mediocre compared to the taste, value and quality offered by Mediterranea.
