Which restaurants next?

I finished fast food court, flipping pancakes and sports bar. My choices are:

- bakery
- rock & roll bar
- crazy dog’s carnival
- gourmet restaurant
- pizzeria
- indian diner
- seafood bistro
- breakfast cafe
- vilnius manor
- the lost oasis

Note that I am low on gems and I’ve been playing the first three earning coins so I can play in the casino. Help me pls

right now I’m considering the lost oasis cause its the cheapest. should I go for it or are there other restaurants that are more worth it?
