^My understanding is that the rule is that diners can remove their masks at their table, but need to put them on to get up, use the restroom, upon leaving their table for anything. Servers are supposed to wear their masks at all times. We put on our masks while the server is taking our order, placing plates, etc.
Bistro Eloise has the spacing of the tables right. They might even have more seats outside than in their dining room Plaka, the Greek place next door, well it felt a little tight to me.
