Don't know if the Roma site uses Open Table, but here's what happens to us when trying to access information on their site. My wife's phone is on Airplane Mode, so she only has access to the internet via wifi, mostly SBR wifi. My phone is not on Airplane Mode, and wifi is turned off because SBR wifi comes up as not secure, so to be cautious, I use cell towers. In particular, right now I'm on Chippies.
Now, yesterday, I would Google Roma's Restaurant SXM and get this screenshot. If I clicked on Find a Table or Menu, I would get this screenshot. Then I found out that if I clicked on the call button, they wouldn't answer the phone. Frustrating.
