I have read some comments about lots of people being sick and the suggestion that momos can be a problem. I have been really looking forward to trying them. Are there recommended places to go to and to avoid in Kathmandu and Pokhara? Is it an issue of bad hygiene, meat being undercooked or just unlucky? Are vegie momos ok in most places and on Annapurna Base Camp trek? We plan to be vegetarian on trek for better stomach safety and respect for their religious beliefs .
