Every meeting of Tikkun Leil Shabbat includes a vegetarian pot luck dinner. 

What kind of food should I bring?
Please bring a vegetarian entrée or salad to share. Your dish should fit into one of two categories:
1. Option One: Bring a vegetarian contribution (no fish please; dairy and eggs are fine). There's a table where you can place that contribution.
2. Option Two: Prepare your potluck contribution in a hekhsher-only kitchen, or purchase a hekhshered potluck item. There's a designated table where you can place that contribution. (If you don't totally understand Option Two, don't stress; just go with Option One, above.)

I keep kosher in a particular way. Will I be able to eat dinner at TLS?
There is always one table of vegetarian food, and another table of vegetarian food that is hekhshered or prepared in a hekhsher-only kitchen. This makes it possible for as many of us as possible to eat and to contribute food. (Learn more about the "two-table" potluck phenomenon here.)
After services, a handful of participants fill kiddush cups with a wine or grape beverage of their choice, and Tikkun Leil Shabbat participants all say kiddush together. After a break to allow for ritual handwashing, we say a communal motzi over hekhshered challah.
