There’s a Cars n Coffee meet in Liverpool that’s pretty good, this used to be the last Sunday of each month at the Chung Ku Restaurant (by Land Rover and Jaguar main dealerships), free to attend but best to get there before 9am in order to get a parking space as it can be really busy - not announced when it will resume yet, there are usually a few Lotus’ but the range of other interesting cars that turn up is pretty impressive.
There is also a different Cars n Coffee on the Prom meet at Rhos on Sea (North Wales) that was held on the 3rd Sunday of each month between April and September near the Cayley tea hut. Free to attend and if you get fed up of looking at cars you can stare out to sea or go and build sand castles on the beach. Nothing announced atm as to when this will resume either.
Just remembered that the Scotch Piper Pub (Southport Rd, Lydiate, Liverpool L31 4HD) used to have fairly regular gatherings of bikes and cars both in the evenings and of weekends, never attended any but have driven past when they have been on often enough and there has been some interesting stuff there too.
NORLOG (North west Lotus owners group) also arrange meets etc and have a website that information can be found on as to what is likely to happen and when...
http://www.norlog.net/There are occasionally some classic Lotus in attendance but the majority are generally Elise, Exige, Evora.
LDC used to be the more active choice if you like driving your car (routes planned, track days etc), Club Lotus meets where more suited to Jazz enthusiasts (nothing wrong with Jazz I hasten to add but they have their own clubs...!).
