Be upfront :

If you’ve had only brief interactions with someone you want to get to know better, it’s absolutely okay to share that you’re looking to meet new people and that you’ve really enjoyed the conversations you’ve had so far. Being direct about your desire to make new friends doesn’t have to be a big scary thing. Casually let them know that you’d be happy to chat again or get together in a different context (e.g., “Hey! I really enjoyed our conversation! Any chance you’re open to grabbing a coffee sometime?” or “I actually just moved here and don’t really know anyone. I’d love to find time to hang out and maybe go for a walk together!”). People are often far more receptive to this than we expect. They might even be relieved that you made the first move!
