Went in June.
Firstly had a cracking time, so many green areas littered around Riga, lots of new development as well so its not run down at all really. Travelled by taxi to the nearest beach one day and that was really nice as well, all redeveloped with new shops and restaurants with a long promenade type thing. Big town hall with traditional dancing going on.
Prices for food and beer were all reasonable, locals were friendly enough and helpful. Wasn't much in the way of clubs but lots of pubs/bars littered around.
Would definitely recommend for anyone thinking of going.
