Leicester Vegan Fair - suggest combining a visit to this with a tour of the city and a meal in a restaurant.
Trains from Nottingham to Leicester seem to be about every 30 minutes and take about 30 minutes (£9.80 return) - 9:28;10:02:10:28 - I plan to get the 10:02 (quiet coach) and will wait a few minutes at the exit of Leicester station - text/call me on mobile if you can not find me.
Directions from railway station to Avenue Primary School (30 minutes walk - 15 minutes by bus no. 44)
Possible meal at
Shivali - South Indian Vegetarian Restaurant close to the station
Mirch Masala - Market Street
