Georgian to English Art/Literary Poetry & Literature Literature

Two women are chatting in New York. One suggests they go to eat some Acharuli khachapuri at a new Georgian restaurant that has just opened. The reply is:

რა აჭარული-მეთქი, გოგო?

I'm not sure what this means. Is she expressing surprise that they have Acharuli khachapuri in New York?

After the first woman (who lives in New York) explains about the new restaurant, and says she's been going there every week because the khachapuri is so good, the second says:

აბა, შენა ხარ-მეთქი.

Does this mean "What are you like??" (as in "You're crazy!" or something like that)?

The first woman replies:

ეგ არი ნეითივი ვარო?

I also don't really understand this. Is it something like "Are you suggesting I'm a native New Yorker now?"

Sorry for the complicated question. Hope it's not too confusing. Thanks in advance.
