Robelle is a flat town with condensed wooden buildings. The town has a bridge that leads to them. This town also has one restaurant where people go to eat.
Dr. Hiriluk went to Robelle with Tony Tony Chopper to treat the people out there who were sick. When they arrived on the Island, they peaked over the edge of the town's Bridge to eavesdrop on its security force. They used this opportunity to find and treat the sick townspeople but were driven off for using quack medical practices.
Just a week before the Straw Hats arrived at Drum Island, Portgas D. Ace visited Robelle and went to a restaurant. Due to Ace's devil fruit powers, it didn't snow in the town that day. Ace gave the townspeople Luffy's wanted poster and told him to tell Luffy that he would wait for him in Alabasta for ten days. He told the townspeople his name but before he could say anything else, the owner of the restaurant where Ace ate in yelled at him for not paying for his food, Ace then fled the scene in haste.

A. No, as the two people Ace had interacted with went to inform and give Dalton Luffy's wanted poster, but they arrived late and the Straw Hats had already left.
