I spoke to Angie at Dinah's. She said that they have not yet gotten a definitive answer as to reopening. It is possible they won't restart indoor dining on Friday, as previously thought. I'll call Dinah's again on Friday
Even if the are nominally open for business on Monday, it is probable there will be rules in place that may preclude our meeting.
So, bottom line, it is not looking good for us in May. However, I’m reserving judgment until I have more definite news.
Meanwhile, thank you for your forbearance and patience.
