Why would a usually popular restaurant be completely empty now?

like whats going on with the economy these days , is some trendy restaurants on the waterfront where i live , May isn't as busy as the summer tourist season but patio's are now open and usually there'd be some people on them but yesterday i was there around 2-3 pm in the day and like literally this one spot which is normally popular there patio was entirely empty like not 1 table

and both sections were empty , is a top and bottom , both the servers were like playing on there phones or doing nothing , the weather was not perfect but not cold or raining , not sure if it got busier later i left to go to the gym

like not a single table? maybe time to talk to the owner about making some changes or figuring out what the issue is

according to google maps its busier now than yesterday but can't see it from where i live to verify but its also Friday so likely more customers than yesterday. but still very odd that there would be days and times of the week when there is literally ZERO customers present especially in May
