I'm meeting a friend from overseas who is in the UK for a rare visit this week. We've realised we can both get to Brighton. Can someone recommend somewhere we can meet for lunch? We haven't seen each other since before Covid so we want somewhere that we can linger as long as we want e.g. a good coffee shop that does something slightly more substantial than a snack. She has very limited mobility so it needs to be somewhere she can get a taxi to drop her outside and ideally with a loo on the ground floor.
We might also want something to do in the afternoon. She can't stand for long or walk far so wandering around isn't an option. Any ideas please?
