Funchos
If you're out on the end of long Island and you're looking for real authentic Mexican, Funcho's is the best place for the job. I truly think I make up excuses to go to Riverhead now just to stop here on the way. The menu is cheap but delicious and if it's summer sitting outside makes the experience even better. From the tacos to the burritos to the classic glass real Coke you can't go wrong. Make sure to have a side of home made guacamole and chips and if u still have room, for dessert grab some homemade churros for the road (or sneak over to Snowflake next door for homemade ice cream.)
