Hi UK NA, and welcome to MySwissAlps!
>> I'm travelling to switerzland in January 2018 for 4days with my wife. Where staying at *Hotel du Léman - Jongny chemin de la Fontaine 2, 1805 Vevey, Switzerland. How much wil it cost to get there by train or buses ?
To calculate a fare, we need to know where you are starting from. If it is Geneva Airport, the adult full fare is CHF 36.60 each.
If you are staying for 4 days, and plan on using trains, buses, boats and funiculars, you might find it worth your while to buy a Swiss Travel Pass.
>> Is there any vegetarian places to eat ?
Vegetarians usually have no problems finding places to eat in Switzerland.
>> What can I do for 4days there ? Are there any tours close by ?
