Need recommendations.

Hello everyone, we’re two 25 yo guys visiting Armenia for the first time and so far it’s really fun. We’re staying in Yerevan and saw most parts of the city and went to Genri and Geghard so far and planning to travel around more. We’re looking for some restaurants that offer authentic Armenian food preferably around Yerevan. We’re also thinking of going to a water park or pool if you can recommend anything that would be great. And any recommendations for the nightlife here would be great, we already went to beatles pub but couldn’t find anything else on google. Thank you all in advance.
