Near where i live on marjanishvili, there are many shuarma stalls.
Many of them are pretty good, the one near the metro is decent, the one that looks like a diner is very good and there are a couple of others as weell.
But, the best one i have found thus far, has just opened about 50 meters past the populi on marjanishvili.
For 3 lari, you can get a super tasty, good sized shuarma.
The meat they use is really good, all the vegetables are fresh, the cilantro(coriander) mix they have is delicious, and the guys who run it are super friendly and cool.
If you're in the area and hankering for a shuarma, you should defiantly stop in there and get one!
I've only ever had the 3 lari offering but that have several different prices from 3 to 12 lari.
If anyone knows of other good places, let me know!
