A tanong with S05E07

Could anyone tell me what exactly this conversation in S05E07 means?
Eli: What's not to like? I'm likeable, right?
People like me.
Mel:Yeah, we like you.
Eli (to Mel):Well, that's a start.
(to Jim)Jim, could you step it up, there? I got a petsa at the wine bar at Lento's.
Jim:Count me in there.
Is Eli asking Jim to hurry up cuz he's got a date? And is Jim saying he wants to be part of the petsa or that he wants to go to lento's too?
Could anyone help me with this? I'll be waiting.
A millions thanks!
