Found a Brazilian restaurant in Uptown Elizabeth, near the border of Hillside, called Peniel Shalom today.
From first impressions, this small shack serves as a local deli and grill for Portuguese community in the area.
I went with a chicken and cheese coxinha and the lunch-portion Picanha on the menu.
I also noticed that they have a daily blackboard of specials that all seemed good, that I may try next time. Dishes such as Shell steak, Chicken Tropical, Chicken Marsala, etc.
The coxinha was sadly pretty lackluster. Most of the places I've been don't make these fresh, and often sit in warmers next to empanadas. The best coxinha I've ever had was made fresh, and was from Hillside at Sandubao Lanches, mentioned earlier in the thread.
The picanha was cooked well, of good quality, and was a good portion for the "1/2 lunch portion" for $12 and came with rice, beans, and a side salad.
If I return again, I will probably go with one of the daily specials, instead of a steak, as if I'm craving Brazilian steak, I'm better off going to Taste of Brazil in Hillside, the buffet-style rodizio place, similar to Sabor in Long Branch.
